SO.. I have a 72 240z that i rebuilt over the summer l24 with e88 head, EVERYTHING STOCK.
It has been running great for these last 6 months however this morning, starting up was harder than normal and when it finally started i immediately noticed what i felt and heard to me the engine not running on a cylinder or maybe more. (car shaking, unusual
exhaust pattern, different smell from the exhaust)
I drove it for a little trying to trouble shoot and feel but did not go over 2k rpm because engine felt real unbalanced.
It being winter break i cannot reach my autoshop teacher and am now asking..
what do you think the problem might be?
now you have to take in the fact that Ive fixed a blown head gasket on this car and have also pulled a l28 out of my other z so i do have a good understanding of how an engine works and know my way around this car, and today i have thought of a few things that might be the problem
1) water in gas tank
2) distributor points
3) air or fuel blockage of some sort
Today has been very wet and cold so i have not had time to look at any issues, im simply asking for friendly input.
Oh, last night i drove the car without letting it warm up at all. not sure if that matters wasn't going past 3 grand when driving
